General points

The Twinjet spreading boom makes it possible to spread slurry in a traditional way by means of a ‘‘dual-nozzle’’ system. The two pipes have a swinging scatterer at their end, allowing to spread over a very large width.
The swinging scatterer is activated by the spreading pressure, combined with an ingenious mechanical system.
Thanks to this design, slurry is thrown out alternately in one and the other direction, so that these "umbrella"-like jets offer a very low air resistance.

Direct feeding: without macerator

The distribution box has two Ø 125 mm outlets with quick coupling and a deflecting plate holding back the foreign bodies. The stone trap is emptied by an access to the distribution box.

Hydraulic folding

All booms are fitted with a hydraulic folding system that has an insignificant overhang and that does not affect at all the driving of the carriage. During transport, the whole is fastened by a boom clipping system These has a height adjustment device and a craddle with a damping rubber.

The hydraulic folding system has the following specifications:

• hydraulic safety device;

• locking of the boom wings in transport position thanks to interlocking supports;

• diagonally positioned rams (not vertically) to better hold the boom in position (reduction of the swinging movement).

For a higher safety, the folded boom is such that the position of the macerators is pointed inwards so as not to exceed the boom size. From 18 m wide, a double folding system is required.

Macerator

The macerator is of utmost importance in order to make sure the spreading implement works properly. 9 m booms have one single macerator, while those from 12 m have two of them in order to get a greater reactivity at the beginning of the spreading phase and to reduce load losses (slurry is more uniformly spread).

Anti-crash

JOSKIN booms are all standard fitted with the anti-crash device that offer an extra safety when working on hilly ground. Every boom wing is fitted with springs and articulations that, when spreading on a bumpy ground, retract the ends of the boom (max. 55 cm) if it hits the ground. Mounting the wings at the end of the oblong holes allows them to pivot and makes it possible to adjust their height.
